Patent number: 11807589Abstract: A process, a system, and an apparatus are provided for converting a lower alkane to an alkene. Oxygen and a lower alkane are provided to an ODH reactor. At least a portion of the lower alkane is converted to an alkene and an ODH stream comprising the alkene, an oxygenate, water, and carbon monoxide is produced. The ODH stream is provided to a water gas shift/hydrogenation (WGS/H) reactor including a WGS/H catalyst. The ODH stream is reacted within the WGS/H reactor and hydrogen and carbon dioxide are generated from the carbon monoxide and water. At least a portion of the oxygenate and hydrogen are converted to an alcohol. Additionally, the alcohol may be dehydrated to form additional alkene and water.Type: GrantFiled: December 20, 2019Date of Patent: November 7, 2023Assignee: NOVA Chemicals (International) S.A.Inventors: Shahin Goodarznia, Vasily Simanzhenkov, Bolaji Olayiwola, Yipei Styles
